The system of linear equations by graphing

(1,2)

or

x = 1

y = 2

Step-by-step explanation:

To solve the system of two linear equations by graphing, plot the graphs of both lines (linear equation represents the line).

1. The line with the equation intersects the y-axis at point (0,7) and the x-axis at point . Connect these to points with the straight line.

2. The line with the equation intersects the y-axis at point (0,4) and the x-axis at point . Connect these to points with the straight line.

he point of intersection (1,2) of these two lines is the solution to the system of two linear equations.

f is the midpoint of

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
